cloudflare

问题 In one of projects we use CloudFlare and its cf-connecting-ip header to get a visitor IP address. But I'm not sure that the info can be fully trusted. For example, a bad user somehow had obtained real IP of our server, and connecting directly to it, putting fake IP address to the cf-connecting-ip header, and pretending that it was a legitimate CF-proxied request. I examined headers for CF-proxied requests, and saw the cf-request-id header. But it's unique per a request, and I cannot see there

问题 So i have created an automation bot to do some stuff for me on the internet .. Using Selenium Python..After long and grooling coding sessions ..days and nights of working on this project i have finally completed it ...Only to be randomly greeted with a Error 1015 "You are being rate limited". I understand this is to prevent DDOS attacks. But it is a major blow. I have contacted the website to resolve the matter but to no avail ..But the third party security software they use says that they

问题 We have SignalR Core running in IIS and the connections are not being closed over time. This results in a 503 error: HTTP Error 503.2 - Service Unavailable The serverRuntime@appConcurrentRequestLimit setting is being exceeded. When recycling the apppool the Current Connections will drop to 0 and then back up to around 50 (as actual clients reconnect). Over the course of a day it can easily reach 2000. Not every connection is leaking - the number does decrease but trends upwards over time.

问题 I am trying to get mutual client certification to work in Azure. I am running a web app with this configuration: public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services .AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme

问题 I would like to use chromedriver to scrape some stories from fanfiction.net. I try the following: from selenium import webdriver import time path = 'D:\chromedriver\chromedriver.exe' browser = webdriver.Chrome(path) url1 = 'https://www.fanfiction.net/s/8832472' url2 = 'https://www.fanfiction.net/s/5218118' browser.get(url1) time.sleep(5) browser.get(url2) The first link opens (sometimes I have to wait 5 seconds). When I want to load the second url, cloudflare intervens and wants me to solve

问题 I'm using CloudFlare to implement a REST API. I need to add some notifications which are implemented with socket.io on Node.JS. When socket.io uses a live connection to keep client updated it will work because the connection is established between server-client, but what happens when socket.io does polling? Does CloudFlare use always the same server for each client? 回答1: WebSockets are standardised by the IETF in RFC 6455, this allows you to avoid polling behaviour and instead directly

问题 I'm wanting to put Cloudflare in front of my API hosted on Cloud Run. I'd like to ensure my Cloud Run app only accepts connections from Cloudflare (to avoid bypassing DDoS mitigation + rate limiting in Cloudflare). Is there any way to use Cloudflare's Authenticated Origin Pulls with Cloud Run? Other solutions that achieve the same effect are welcome too - however the key is I don't want traffic from non-Cloudflare sources to trigger a Cloud Run invocation (otherwise a DDoS could result in
